The user is trying to do a trend of one tag, and it seems to work for 1 week, 2 weeks, 1 month. When he tries to do it for 3 weeks though he gets bad data.
Product Version: 9.2
The user is likely either choosing three weeks incorrectly, or has bad data in that section. Since the one month works fine though, I am having the user plot out just that 1 week in question to see what he gets. They are going to look at the raw data to see if there is a problem, but it is likly just user error.
